Official Title: The Effect of Prolonged Effort on the Bilateral Asymmetry in Trans Tibial Amputee Running With Running Specific Prosthesis

Brief Summary: The purpose of this study is to determine the effect of prolonged effort in long distance running on the biomechanical bilateral asymmetry in the lower limbs of trans tibial amputee running with running specific prosthesis.

Sponsor: Sheba Medical Center

Current Primary Outcome:

  • The changes in step length asymmetry after prolonged effort in running on a treadmill. [ Time Frame: Several measurements during 20-30 minutes run. ]
    Step length will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run.
  • The changes in contact time asymmetry after prolonged effort in running on a treadmill. [ Time Frame: Several measurements during 30 minutes run. ]
    Contact time will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run.
  • The changes in flight time asymmetry after prolonged effort in running on a treadmill. [ Time Frame: Several measurements during 30 minutes run. ]
    Flight time will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run.
  • The changes in hip angles asymmetry after prolonged effort in running on a treadmill. [ Time Frame: Several measurements during 30 minutes run. ]
    Hip angles will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 3
